QUICK START GUIDE

1. Connect the positive and negative terminals of the load to the VOUT and GND pins,

respectively.

2. Preset the power supply output between 8V and 18V, and then turn off the power supply.

3. Connect the positive and negative terminals of the power supply output to the VIN and GND

pins, respectively.

4. Turn the power supply on. The MP8763DGLwill automatically startup.

5. To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 2V to turn

on the regulator or less than 0.4V to turn it off.

6. Use R1 and R2 to set the output voltage with VFB = 0.611V. Follow the Application Information

section in the device datasheet to select the proper value of R1, R2, inductor and output

capacitor values when output voltage is changed.

7. If lower ripple at light loads is needed, then use 1.2μH or 1.5μH L1. But with the larger L1, the

transient response peak to peak value will become larger too.
